Hmm, xmlSecDsaKeyGenerate is returning -1 for me.
The console says:

<..\src\dsa.c:533>: error 100: assertion : key != NULL

Here's the input:

xmlSecKeyPtr key = NULL;
DSA * dsa = NULL;
char *passwd = "";
std::string prvkey_str;
int retval = 0;

prvkey_str is
-----BEGIN DSA PRIVATE KEY-----

Code:

BIO * mem = BIO_new_mem_buf(
            const_cast<void *>(static_cast<const void *>(prvkey_str.data())), prvkey_str.size());
dsa=PEM_read_bio_DSAPrivateKey(mem, NULL, NULL, passwd);      
retval = xmlSecDsaKeyGenerate(key, dsa);

Any ideas?

Thanks,
